Patent number: 8538188Abstract: A forensically sound image of a computer readable storage medium can be transferred across a low bandwidth communications network. The method can include the step of scanning an image of the computer readable storage medium for redundant data, the redundant data duplicative of locally stored data. The method can also include generating a skeleton image based on the image of the computer readable storage medium by excluding the redundant data from the image of the computer readable storage medium. The method can include transmitting, by a transmitting device, the skeleton image over the communications network to a receiving device to enable reconstruction of an image copy of the computer readable storage medium using the skeleton image and the locally stored data. A receiving device can reconstruct a bit-for-bit copy of the image of the computer readable storage medium.Type: GrantFiled: August 4, 2009Date of Patent: September 17, 2013Assignee: Mitre CorporationInventors: Kathryn R. Watkins, Michael McWhorter, William H. Hill, Jeffrey W. Long, Christian Shrauder

Publication number: 20100189991Abstract: A method is disclosed to fabricate carbon foams comprising a bicontinuous network of disordered or irregular macropores that are three-dimensionally interconnected via nanoscopic carbon walls. The method accounts for (1) the importance of wetting (i.e., matching the surface energies of fiber to sol) and (2) the viscosity of the microheterogeneous fluid filling the voids in the carbon paper. Carbon fiber papers are mildly oxidized by plasma etching, which greatly enhances the uniform uptake of resorcinol-formaldehyde (RF) mixtures.Type: ApplicationFiled: November 17, 2009Publication date: July 29, 2010Inventors: Justin C.
